What are synthetic fibres made from?

• Synthetic fibres are made from polymers derived from petrochemicals.

• Synthetic fibres are made from natural plant fibers.

• Synthetic fibres are made from animal proteins.

• Synthetic fibres are made from metals and minerals.

Name two types of synthetic fibres.

• cotton

• polyester, nylon

• silk

• wool

What is the main property of nylon?

• Highly absorbent and porous.

• Lightweight and flexible.

• Biodegradable and eco-friendly.

• Durability and strength.

How does polyester differ from cotton?

• Polyester is softer and less expensive than cotton.

• Cotton is synthetic and more durable than polyester.

• Polyester is synthetic and more durable; cotton is natural and softer.

• Polyester is more breathable than cotton.

What is a common use of acrylic fibres?

• Medical devices

• Automotive parts

• Textiles and clothing

• Construction materials

Which synthetic fibre is known for its elasticity?

• Spandex

What are the properties of plastics that make them useful?

• Plastics are heavy and fragile.

• Plastics are only biodegradable.

• Plastics are expensive and difficult to mold.

• Plastics are lightweight, durable, moisture-resistant, chemically resistant, moldable, and cost-effective.

How do plastics resist moisture?

• Plastics are made from natural fibers that attract water.

• Plastics resist moisture due to their non-polar structure and low water absorption rates.

• Plastics absorb moisture due to their polar structure.

• Plastics resist moisture because they are biodegradable.

What is one environmental concern related to plastic use?

• Improved air quality

• Reduction in greenhouse gases

• Increased wildlife habitats

• Ocean pollution due to plastic waste

How do synthetic fibres contribute to pollution?

• Synthetic fibres are made from natural materials.

• Synthetic fibres contribute to pollution by releasing microplastics, using harmful chemicals in production, and not being biodegradable.

• Synthetic fibres are fully biodegradable.

• Synthetic fibres do not require any chemicals in their production.
